STRINGSTRING
FRE7 protein (Saccharomyces cerevisiae) - STRING interaction network
"FRE7" - Putative ferric reductase with similarity to Fre2p in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

FRE7Putative ferric reductase with similarity to Fre2p; expression induced by low copper levels; Cell surface metalloreductase. May be involved in copper homeostasis (620 aa)    
Predicted Functional Partners:
FRE8
Protein with sequence similarity to iron/copper reductases, involved in iron homeostasis; deletion mutant has iron deficiency/accumulation growth defects; expression increased in the absence of copper-responsive transcription factor Mac1p; Required for the uptake of Fe(3+) ions. May participate in the transport of electrons from cytoplasm to an extracellular substrate (Fe(3+) ion) via FAD and heme intermediates (By similarity). Involved in iron homeostasis (686 aa)
           
  0.829
FTR1
High affinity iron permease involved in the transport of iron across the plasma membrane; forms complex with Fet3p; expression is regulated by iron; Permease for high affinity iron uptake (404 aa)
     
   
  0.763
CTR3
High-affinity copper transporter of the plasma membrane, acts as a trimer; gene is disrupted by a Ty2 transposon insertion in many laboratory strains of S. cerevisiae; Required for high affinity copper (probably reduced Cu I) transport into the cell (241 aa)
     
   
  0.761
FTH1
Putative high affinity iron transporter involved in transport of intravacuolar stores of iron; forms complex with Fet5p; expression is regulated by iron; proposed to play indirect role in endocytosis; High affinity iron transporter probably involved in transport of intravacuolar stores of iron (465 aa)
     
   
  0.723
FET3
Ferro-O2-oxidoreductase required for high-affinity iron uptake and involved in mediating resistance to copper ion toxicity, belongs to class of integral membrane multicopper oxidases; Iron transport multicopper ferroxidase required for Fe(2+) ion high affinity uptake. Required to oxidize Fe(2+) and release it from the transporter. Essential component of copper- dependent iron transport (636 aa)
     
   
  0.678
FRE1
Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters; expression induced by low copper and iron levels; Metalloreductase responsible for reducing extracellular iron and copper prior to import. Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores. Fe(3+) is reduced to Fe(2+), which then dissociates from the siderophore and can be imported by the high-affinity Fe(2+) transport complex in the plasma membrane. Also participates in Cu(2+) reduction and Cu(+) uptake (686 aa)
       
 
0.669
FRE2
Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters; expression induced by low iron levels but not by low copper levels; Metalloreductase responsible for reducing extracellular iron and copper prior to import. Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores. Fe(3+) is reduced to Fe(2+), which then dissociates from the siderophore and can be imported by the high-affinity Fe(2+) transport complex in the plasma membrane. Also participates in Cu(2+) reduction and [...] (711 aa)

FET5
Multicopper oxidase, integral membrane protein with similarity to Fet3p; may have a role in iron transport; Iron transport multicopper oxidase, which is required for Fe(2+) high affinity uptake. May be required to oxidize Fe(2+) and release it from the transporter. Essential component of copper-dependent iron transport (622 aa)

SMF3
Putative divalent metal ion transporter involved in iron homeostasis; transcriptionally regulated by metal ions; member of the Nramp family of metal transport proteins; Has a role in controlling the cellular iron ion levels. Mobilizes vacuolar stores of iron in conditions of low iron levels (473 aa)
     
   
  0.635
MAC1
Copper-sensing transcription factor involved in regulation of genes required for high affinity copper transport; Regulatory protein involved in Cu/Fe utilization and stress resistance. Involved in basal level transcription of FRE1 and H(2)O(2)-induced transcription of CTT1. Regulates the transcription of CTR1 and CTR3 via the copper ion responsive elements in their promoters. Required for degradation of CTR1 (417 aa)
